F-AUCETOR COCK.

SPECIFICATION forming part of Letters Patent No. 761,973, dated June 7, 1904'.

Application filed May 11, 1903.

To all whom, it may concern:

Beit known that I, HERMANN KUPsoH, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Faucets or Cocks; and I do hereby declare the following to be a full, clear, and exactdeseription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a novel construction in a faucet or cook, the object being to provide a slow-closing cock in which pounding due to sudden shutting'ofi is entirely avoided and in which the flow of Water can be regulated at will; and it consists in the features or construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is a central vertical@ section of a faucet or cook constructed in ac-; cordance with my invention, showing the valve closed. Fig. 2 is a similar section showing the valve open.

Referring now to said drawings, A represents the water-inlet, B the water-outlet, and C a horizontal valve-seat interposed between the water inlet and outlet and surrounding the opening establishing communication between said inlet and outlet. Above said valve-seat O is a vertical cylindrical chamber D, in which a trunk piston-valve E is longitudinally movable, said valve being of larger diameter than said valve-seat and seating thereon. A cylindrical extension F on the lower end of said valve E enters said opening surrounded by said valve-seat O. The upper end of said chamber D above said valve E forms a fluidpressure chamber which communicates with the water-supply through passages G and H opening into a groove I in the periphery of said valve extending from the lower end of the latter to a point just above the mouth of said passage G. The passage H is central and opens into the hollow upper end ofsaid valve E. The upper end of said chamber D is enlarged and internally threaded, the shoulder at the lower end of said enlarged portion form- Serial No. 156,701. 'fNo model.)

ing a seat for the lower end of a sleeve J, which enters said enlarged portion of said chamber D. At its lower end said sleeve J is provided with a peripheral groove K, which "communicates by means of radial passages L with the outlet B.

The operation of my device is as follows: When the valve O is closed, the pressure in the chamber above the valve E is equal to the service-pressure, and by reason of such pressure acting on a larger surface at the upper than at the lower end of said valve the latter is held firmly closed by the excess of pressure on its upper end. As soon as said valve O is opened and the pressure on the upper end of the valve released the latter will be instantly raised, the .water displaced by said movement passing out through the duct S. As said valve E rises it strikes the projection Q, which limits its upward movement, so that the initial' opening of said valve is so limited as to admit'of only a limited flow of, water. By further revolving the valve-stem N the latter andsaid projection Q are raised and the valve E follows, thereby gradually increasing the flow'of water. There will be a very slight flow of water through the passages G and H and duct S; but by reason of the very limited size of the passage G such flow is insufficient to produce a pressure above the valve E, so that there can be no leaking at the upper end of the sleeve J or enlarged portion of the chamber D. Hence it is unnecessary to pro- .videstufling-boxes to prevent leakage. As said valve O is again closed the valve E will slowly close also partly by gravity and partly by accumulation of water in the chamber above said valve and the equalization of pressures 0n the differential areas. The valvestem N is turned by means of the button U at its upper end.

This faucet or cock has many advantages, the wearing parts being entirely protected against misuse by the exercise of too much power by the operator and the flow of water being capable of regulation as desired, while sudden shutting off of the flow and consequent pounding are rendered impossible.

On said projection Q at its lower end is a nut or collar Q, which is adapted to prevent the valve-stem N from being entirely withdrawn.

I claim as my invention 1. In a faucet or cook, the combination with a fluid-pressure-aetuated piston-valve in the body thereof, and an auxiliary valve controlling the movements of said piston-valve, of a threaded sleeve in which the stem of said auxiliary valve moves, and a projection on said auxiliary valve adapted to limit the opening movement of said piston-valve to regulate the flow of Water.

2. In a faucet or cook, the combination with a fluid-pressure-actuated piston-valve in the body thereof, of an auxiliary valve controlling the movements of said piston-valve, and devices eontrolled by said auxiliary valve and engaging said piston-valve for limiting the opening movement thereof to regulate the flow of water.

3. In a faucet or cook, the combination with a fluidpressureactuated main valve in the body thereof, of an auxiliary valve controlling the opening and closing of said main valve, and devices controlled by said auxiliary valve and engaging said main valve to control the degree of opening thereof to regulate the flow of water.

4. In a faucet or cock, the combination with a fluid-pressure-actuated main valve in the body thereof, and an auxiliary 'alve controlling the opening and closing of said main valve, of an adjustable stop controlled by said auxiliary valve and engaging said main valve when open to limit the degree of opening thereof to regulate the flow of water.

5. In a faucet or cook the combination with a fluid-pressure-actuated main valve in the body thereof, of an auxiliary valve controlling the opening and closing of said main 'alve, and a stop located in the path of said main valve and moving simultaneously with said auxiliary valve for limiting the degree of opening of said main valve and regulating the How of water.

6. In a faucet or cook, the combination with a fluid-pressure-actuated main valve in the body thereof, and an auxiliary valve controlling the opening and closing of said main valve, of a movable stop located in the path of said main valve for limiting the degree of opening thereof, and operating means common to said auxiliary valve and said stop for opening said main valve and adjusting said stop.

7. In a faucet or cook, the combination with a fluid-pressure-aetuated main valve in the body thereof,a valve-stem longitudinally movable in said body, and an auxiliary valve on said stem controlling the movements of said main valve, of a projection on said valve-stem and auxiliary valve projecting into the path of said main valve and adapted to act as a stop to limit the opening movement of said main valve, whereby the flow of water can be regulated.

In testimony whereof I aflix my signature in presence of two witnesses.
